Working principle of Force type gas water heater
- Feb 07, 2018 -

The Force type gas water heater is forced to exhaust smoke through a exhaust motor set up above the water heater so that the burning exhaust gas is quickly discharged out of the outdoor. Through an external plug for gas water heater power supply, the internal parts are: pulse igniter, ion sensor, temperature controller, pressure switch, fuse (some gas heater), starting capacitor, fan motor, micro switch control valve, solenoid valve, water control valve, a water gas linkage device. The burner, a circulating water tank, the total circuit control package, ignition indicator, temperature indication screen (not old), gas proportional valve (old no), scientific development of some new technology, gradually have some new parts added in, there are some common components.

In electricity, water, ventilation conditions, due to the pressure of the water flow to open the microswitch, the exhaust motor starts to work at the same time exhaust, ignition pulse discharge, gas control solenoid valve to open the flow of gas through the gas into the combustion chamber, encountered electric spark ignited, heating a circulating water tank, hot water in the cold water discharged soon after outflow. If the water temperature is higher than fifty degrees, limit the temperature controller to work, cut off the power supply and extinguish the gas. If the outdoor air pressure is too large or the flue is blocked, the long time use of the circulating water tank will lead to the melting and adhesion of the radiator and the bad ventilation. The wind switch will turn off the power and the gas water heater will stop working. Usually the wind pressure switch is more prone to failure, showing that the gas water heater can start, but automatically extinguish the fire for a few seconds or several minutes.
